Embodiment Construction
[0043] Such as figure 1 As shown, the present invention is based on the weak mutation test and the self-organizing map neural network clustering method, and obtains a subset of variants without affecting the validity of the test, and reduces a large number of redundant variants to reduce the cost of mutation testing. The example program Triangle.java in Table 3 is taken as an example to describe the method of the present invention in detail.
[0044] Table 3 sample program
[0045]
[0046] (1) Generation of mutant kill matrix based on weak mutation test: use the mutation test tool to perform mutation operations on the programs shown in Table 3, and select AOIS, AORB, COI, COR, ODL, ROR, VDL, AOIU method-level mutation operators A total of 8, generating 198 variants, constructing 198 variant branches corresponding to the 198 variants based on the weak mutation transformation method, inserting the 198 variant branches into the positions corresponding to the sample program, ...
